目的对慢性乙肝肝内病变应用超声进行动态观察,探讨三维超声在慢性乙肝肝内病变发展过程中的价值。方法对实验室检查报告表面抗原(HBsAg)、核心抗体(HBcAb)、e抗原(HBeAg)均阳性的慢性乙肝患者进行肝脏二维超声检查、三维重建,分析图像特点。穿刺活检后,对肝内结节二维、三维超声检出数比较。结果122例HBsAg(+),HBcAb(+),HBeAg(+)患者中,三维超声能较清晰显示肝内增生结节、小肝癌形状及与周边肝组织关系,三维超声对小肝癌的检出数较二维超声明显增多。结论超声能早期发现慢性乙肝肝内结节性病变,三维超声多切面、多角度检查提高了小肝癌诊断准确性。
Objective To investigate the value of three-dimensional ultrasonography in the development of chronic hepatitis B lesions by ultrasound. Methods Two-dimensional ultrasonography and three-dimensional reconstruction of liver in patients with chronic hepatitis B who were positive for surface antigen (HBsAg), core antibody (HBcAb), and e antigen (HBeAg) in laboratory examination were performed. Puncture biopsy, the two-dimensional and three-dimensional ultrasonography of liver nodules were compared. Results In 122 cases of HBsAg (+), HBcAb (+), and HBeAg (+) patients, the three-dimensional ultrasonography showed more clearly the intrahepatic proliferative nodules, the shape of small hepatocellular carcinoma and the relationship with the surrounding liver tissue. Compared with two-dimensional ultrasound significantly increased. Conclusion Ultrasonography can detect chronic hepatitis B intrahepatic nodular lesions early and improve the diagnosis accuracy of small hepatocellular carcinoma by three-dimensional ultrasound multi-slice and multi-angle examination.
